Different states of mind are associated with specific brainwave frequencies that would be inaudible if played directly. These frequencies can be induced in the brain indirectly by playing two different audible tones into each ear, which after being processed by the brain, are perceived as an inaudible beat matching the target brainwave frequency. As you listen, your own brainwaves fall into step with this inaudible beat, and after a few minutes synchronize with the target brainwave frequency. Brain Wave's 35 programs layer these binaural sequences into multi-stage sessions that have helped thousands of people focus and concentrate, feel positive and motivated, and sleep more soundly.

With each pulsed tone, the brain produces an electrical response. The effects one experiences are the creations of the brains reaction to the “tones”, what neurologists call the “cortical evoked response” (the electrical response of the top most cortical layer of the brain). The brain is a mass of neurons, each taking part in storing, retrieving and transmitting electro-chemical impulses: information, colors, images, sounds, smells and tastes. Brainwave entrainment stimulates different areas of the brain allowing for the awakening and subsequent release of various levels of stored material. It also has an effect of  quietening the mind for clearer thought and process.

The activity of neurons generate electric currents; and the synchronous action of neural ensembles in the cerebral cortex, comprising large numbers of neurons, produce macroscopic oscillations. These phenomena can be monitored and graphically documented by an electroencephalogram (EEG). The electroencephalographic representations of those oscillations are typically denoted by the term 'brainwaves' in common parlance.[4][5]
